The embodiment of the invention illustrated by these drawings is asound-reproducing instrument or graphophone whereby any selected one ofa plurality of circular disk records of different diameters may betransferred to the graphophones turntable and played thereon, or eitherselected side of a double record may be played, whereupon the recorddisk is returned to its original position in a rack or holder, suchselection being independent of the order in which the disks are arrangedin the rack.

The illustrated mechanical and electrical organization, and theoperation thereof, are as follows:

Referring now particularly to Figures 1 and 2, the base or frame i ofthestructure has ahorizontal top 2 and a platform 3 parallel therewithand rotatable in alternately opposite directions on supporting rolls 4about a vertical axis concentric with the record-carrying turntable I.

Excepting for the driving motor and its connections and therecord-holding rack designated generally 8, this platform carries theoperating mechanism and devices, some of which are supported above theplatform and others suspended below it extending downwardly throughacircular opening I in the top 2 of the frame. The side 8 of this openingforms a circular track for the platforms rollers 9 which assist inmaintaining the platform in axially vertical rotative position.

This platform and all the parts carried thereby may be lifted andremoved entirely from the base or frame of the structure (for makingrepairs and replacements or other purposes), the machine's vertical mainshaft Ill being removably seated in a socket H in the upper end of itscoaxial driving shaft i2 (rotated as by an electrical motor indicated atH in Figure 31), this shaft Ill being turnable in said socket against aspring-pressed member i3 engaging its flattened side, in case a stoppageoccurs in the driven mechanism. The turntable is keyed at iii to a shaftll aligned with the main shaft l0, and a circular box I! contains acoiled flat spring I 5 whose inner end is fastened at I to said shaft l1and whose outer end frictionally contacts the curved inner side 2. ofthe box which is secured at 2| to main shaft ll. Thus the turntable isyieldingly driven by this main shaft. The rack or record holder mountedon the top 2 of the structure and indicated generally 6 (to beparticularly described hereinafter) is adapted to contain side by sideand edge up a plurality of disk records 22, extending in the turntablesradial directions. Record-transferring mechanism mounted on the platform3, and hereinafter particularly described, is broughtiby rotating theplatform, into registration with the particular record (in the rack)selected for playing, the particular record side (of a double record)selected for playing being governed by the rotation of the platform inone direction or the other. This platform is rotated for this purpose bythe following mechanism, referring now to Figures 1, 2,3, 4: e

A shaft 23 has teeth forming a pinion ll near its outer end meshing witha continuously toothed endless rack 24 mounted on the downwardlyextending bracket 25 which is secured to the structures top 2 and iscurved in a horizontal plane concentrically with the platform's axis ofrotation.

The teeth of this rack extend (as seen in Figure 1) along its opposite(upper and lower) sides, for rotating the platform in oppositedirections, and around the end portions connecting said sides. Saidshaft 23 bears turnably and also laterally-slidably in a vertical slot28 through the downwardly extending arm 21 of the platform 3. As shownin Figure 1 the rack 24 is centrally mounted in an oblong recess 25aformed in the face of the stationary bracket 25; and the shaft 23 has areduced end portion 23a which remains in contact with the walls of therecess and thus holds the teeth of the pinion in mesh with the teeth ofthe rack. This causes the pinion II to travel around on the rack as theshaft 23 is rotated and move the platform back and forth through theconnection of the depending arm 21, secured to the turntabledn which theshaft is vertically guided. To render. this shaft sumciently flexible,its inner end has a head 2| through whose angularly spaced bores 20slidably bear the pins 30 projecting from the side of a gear 3! meshingwith and driven by a gear 32 on shaft 33 carrying the bevel gear IImeshing with and driven by the gear 3' on the main shaft 40 of shaft 23'is meshing with the teeth 01 the upper or the lower side of the rack 24at the time) until stopped in registration with the. particular record'(or the particular side thereof) in the record rack which has beenselected for playing. This stopping of the platform's turning movementis effected by the following mechanism: v

The gear 8i (see Figure 1) meshes with and drives gear 38 on shaft awhose worm 4| meshes with a worm gear 42 on a shaft 43. This shaft (seeFigures '7, 8, 9) carries a cylindrical drum composed of a plurality ofcircular disks ll (twenty in the shown construction, being one disk foreach record side of each disk recordinthe'record rack) disposed side byside, and separated by spacer disks I, having radially extending flanges43. The disks 44 have radially projecting lugs. 41 respectively,angularly spaced uniformly as indicated in Figure 8. I 5 Triggers '43having slots 43 through which passes a horizontal-bar II have a turningand also a vertically sliding movement thereon guided betwen theiiangesit, said triggers being associated with and-actuatedby the disks44 respectively. The gear ratios between the means for rotating theplatform 3 and the means for rotating the disks N is such that theparticular trigger is actuated at the proper time (by its disk 34) whichcorresponds with the particular record selected for playing and intoregistration with which the platform is turned. The vselecting mechanismincludes the following parts operating in the following manner:

The particular trigger corresponding to the selected record disk (or theselected side thereof) is moved from its position shown in solid linesto that seen in dotted lines (Figure 8) wherein it is engaged by the lugll of the. corresponding disk as and is thereby moved against thepressure of a spring 38 downwardlyand outwardly (and out of suchengagement) by the camming action of its inclined inner edge II on thehorizontal rod 32, whereupon spring ll raises the trigger to itsoriginal (solid line) position. The triggers are selectively moved totheir dottedline positions (for and 10) whose magnets are inelectriccircuits 53 respectively having switches or buttons II- for 40 openingand closing the same (Figure 31)i These triggers straddle at 53 thehorizontal rod 33 (being held apart by spacers 8|) can-iedgby-one arm 82of a lever fulcrumed at 34, so that when any trigger is forceddownwardly by the engaging ing 41, it swings this am and the leversparallel other arm 63 down against thepressure of spring I 35, thuscarrying the double-sided catch 31 (piv- 7 oted at ll on arm 83)downwardly far enough to permit spring "to turn the upper end of thiscatchs middle portion II into-a position beneath the free end of a lever.arm 12 (as seen in Figure 5). whereupon spring it raises arm 33 andcatch 31 and lifts arm.I2, thus releasing its shoul-' der I3from'theupwardly extending part ll "of a is horizontal bar I3 slidablymounted at I6 on anotherslidable horizontal bar 'II. Thus released. barI! is slid-by its spring I3 toward the right hand side of'Flgures' 1, 5and-6 causing its inclined right hand end.'i3to cam on the under oo edgeof a lever catch 3|! whose other end II has been engaging the'lower endof a lever 32 fulcrmn'ed at 33 andhaving a fork I connected with clutchmember .33.

This hollow Mind portion 33 ofa horizontal bar 31 (connected at 33 to this lever) from supportingengagement with a pin 89 on a vertically movable bar 90 thus permittingthis bar to fall to the position seen in Figure 5 wherein its fork 9|con- 5 nected to clutch member 92'causes it to engage clutch member 93of an idlergear 94 on the main shaft I0.

It will be seen that clutch members 33, 31- cannot engage while clutchmembers 92, 93 are in .en- .10 gagement. The gear 94 meshes with gear 95on a vertical shaft 96 having the gear 21 of a comv posite elementcomprising cam disks shown in Figures 11, 12, 16, 19 and 23, and inassembled side by side position in Figures 1 and 2 in which as- 15-which the transferring mechanism is operated thereby to transfer arecord to the turntable and,

after an inoperative interval (while-the record is.

being played), said mechanism is operated re- 25 versely'by the rotatingdisks to return the record from the turntable to its position in therack. To accomplish these ends, the cam disks (turning in the directionindicated by curved arrows) have the following parts operating thefollowing con- 30 nections and in the following manner: U The lowest(the toothed) cam disk 98 (see Figures 2, 19 and 20) has in its underside a cam groove III in which travels a roller I02 pivoted on a flatwide bar I33 slldable radially of the plat-g 35 form 3 in a bearing I04,etc. On an upward extension III! of platform 3 is mounted the recordgripping jaws and certain operating parts therefor. The uppermost camdisk I06 (see Figures 2, 11 and 12) has a roller I01 which travels in acam do groove 133 in the plate I09 fastened to the under side of anotherwide flat bar IIO (slidable relatively to and parallelly with bar I03)whose post III bears in a slot II2 of bar IIII, a screw post II3 ofthe-platform 3 bearing in slot I I4 of bar 45- I I0 in therelativesliding movement of these bars.

This upper bar Ilil carries at its outer end a toothedrack II!vertically yieldingly mounted on a threaded pm IIS-surounded by a springI" whosetensionis adjusted by the posts nut Ill. 50 On the outer end ofthe upward extension I05 of the platform 3 are spaced ears I2| havingaligned bearings I23 in which a hollow member II! is (See Figmember II!has agear I22 with which the toothed rack Ili meshes, to turn it, andcarries between said eats a hollow member I21 turnablyfl mounted at I23about an axis transverse to the axis of member 9; This hollow memberI2'I Q has at its outer end spaced arms I23 on which the record-grippingjaws I25 are pivotally mounted at I20 respectively.

Arod I23 is slidable in this hollow member I2I so that its conical.outer end presses between and separates (against the pressure ofsprings I29).

Thisrod I23 hasdiagonal *teeth I'3l with which mesh thediagonal teeth I32 of and I33slidable in hollow member I I9, so that r the sliding movement of rodI33 moves rod I23 radiallylnwardlyxor outwardly. The movement of rollerIll- In canr groove lfl of bar IIIi (see Figures 11 and i2) slides thisbar and by its.

rack I II (meshing with gear I22 of hollow member II!) turns the saidmember and the separated gripping Jaws from the position seen in Figures1 and 11 and in solid lines in Figure 15 to the position shown in dottedlines in Figure 15, wherein they straddle the selected record disk 22 inthe rack. The roller I" now passes out of cam groove I" so that bar IIIremalnsstatlonary, and immediately the turning of cam disk IIIG bringsthe rise III of its peripheral cam I40 to the inturned end I of a leverI42 fulcrumed at I42 on.the upward extension I of platform 3 and movesthe leaf spring let the opposite end of this le turned upwardly in itspassage from the rack to the turntable and by the following mechanism:

The hollow member I21 has a gear or toothed sector I" (see Figures 14,27 and 3B) which is brought into mesh with one or the other of a pair ofinwardly-facing spaced-apart toothed sectors I, I41 on the spaced sidesI48, I49 respectively of a member I" bearing slidably on the ears I2 I,so that when sector I46 is by the sliding movement of member I" broughtinto mesh with sector I45 the hollow member I21 is turned in onedirection, but when sector I41 is moved into mesh with sector I4} saidhollow member is turned in the opposite direction, during thetransferring movement of the record disk. The sector I45 is brought intomesh with sectors I48, I41 respectively by the following means:

The top 2 of the structure has angularly spaced threaded stops I I, I52marking the limits of the oscillation ofthe platform 2. On the upwardextension I "of platform 2 is pivotally mounted at III a catch Ill whoseswinging movement is limited by screw stops I". (See Figure 13.) Aspring II. extending between this .catch and the member I" causes saidmember to slide one way or-the other depending on which way the catch isturned on its pivot I58. If the platform 2 be turning toward stop- IIIor IE2 when the selection of the record-side to be played is made, oneof the catchs extensions I" will strike that stop and turn or trip catchII4 so as to slide member I in the direction which will turn hollowmember I21 in the right direction to deposit the record disk on theturntable with its selected side up in position for playing.

immediately the record has been transferred to the turntable forplaying, the tone arm I is moved to engage its needle or stylus I59-inthe beginning of the record's groove. (See Figures 1, 11, 18 and 23.)The tone arm is mounted on platform 3 turnably about a vertical axiscon-. centric with its supporting member Ill, said memberhaving a radialarm IBI. The tone arm is also movable vertically a sumcient distance toraise the stylus from the record disk and to lower it thereto, by thefollowing mechanism:

The cam disk I82 has in its upper side a cam .groove I" in which travelsa roller I64 on the inner end of a lever I" fulcrumed on a verticalpivot pin I carried by a member I81 pivoted at I on the platform I toturn about a horizontal;

axis, so that this lever swings horizontally during the playing of therecord by the travel of the stylus in the record groove. and also may beswung vertically to a slight degree to lower the stylus into said grooveat the beginning of the playing and to raise the same therefrom at theend of the playing of the record. (See Figures 16 and 23.) The inner endof this lever I65 is normally held in lowered position (to raise thestylus) by the travel of its roller I89 on the long dwell I of a camdisk I1I (see Figure 18) fastened on the under side of the cam disk I08.but is permitted to rise (to lower the stylus) by the passing of thisroller into the dip I13 of cam disk. "I. The lever I6! is connected toarm ISI of the tone arm by a bar I 14 pivoted at I15 on this bar I14 andat I18 on arm IGI, so as to have (in case a large-diameter record diskis being played as hereinafter described) a slight horizontal movementrelatively to its said connected parts. As shown in Figures 1 and 17-this bar I14 at its outer end bears on the convex portion I18 of thevertically adjustable pivot post I16 to hold the tone arm raised.

Mechanism is provided whereby the graphophone is adapted to play recorddisks of different diameters, such as the ten-inch and the twelveinchrecords seen in Figure 15, and to lower the stylus into the beginning ofthe groove of the record disk (of whichever diameter) on the tumtable,which mechanism is described and operates as follows:

When the smaller-diameter (ten-inch) record disk is played, the leverI65 and bar I14 swing together as one; but when the larger-diameter(twelve-inch) record disk is laid on the'turntable to be played, itsedge extending beyond the edge of the turntable (as shown in dottedlines in Figure 17) contacts the upper end of a post I18 carried by thelever arm Ill pivoted at Ill on lever It! and presses this lever armdownwardly. The leg I82 of arm I 80 thus contacts the short arm I" of alatch I84 loosely mounted at I85 on the under side of lever I" movingsaid short arm below and out of holding abutment with a stop I8! on theunder side of lever I65. As a'result of this operation the lever I" isswung by thetravel of roller I84 in groove I 02 without swinging the barI 14 with it (and without turning the tone arm from its outermostposition), this bar I 14 tuming on its pivotal connections I15, I16until the upward projection I21 of lever I65 strikes the edge III of barI14, whereupon the lever I65 and bar I14 swing together and the tone armis swung thereby to a position in which the stylus is over the beginningof the groove of the large diameter record and ready to be loweredthereunto. It will be seen that by this mechanism the stylus is inlowering position at a greater radial distance from the turntables axisfor a large-diameter record than it is for a record of small diameterwhich does not project far enough to rest on the upper end of post I12.

A spring I" mounted at I on lever I65 and at Ill on bar I14 urges themto parallel position. The stylus being now lowered into the outer end ofthe groove of the record disk (of either diameter) by the riding ofroller I69 up into dip I12, and the rotation of the cam disks (includingcam disk 2) ceasing, the record is played and roller I84 'inovesinwardly (toward shaft I1) in the enlarged dwell I92 of cam. groove I63.-When the cam disk "2 was rotating before the playing of the record, itsperipheral cam 22I engaged thearm 222 of a bell crank lever .75

223 fulcrumed at 224 in a block 2I9 on the platform 3 (seeFigures 2, 16,23, 24, and 25).' The other arm- 225 of this lever connected at 226 to amember 2" has thus slid said member downwardly (against spring 232) inits bearing in said block so that the end portion 229 of a long rod 296extending through an opening 2| 4 of a vertical rod 2|5 is in positionto enter a hole 2|6 of said member, whereupon said end portion isinserted into said hole by the pressure of a spring 2I3 whose action ishereinafter fully explained. The arm 222 of lever 223 passing off of cam22| allows spring 232 to raise member 2 and said end of rod 295 with it,thus raising rod 2I5 and disengaging clutch members 92, 93 (see Figure31, etc.) and causing the rotation of the camdisks to cease during theplaying of the record. As the tone arm is turned, its arm I93 (seeFigures 11, 16, 23 and 26) moves with it. This arm has looselymounted'at I94 thereon on arm I95 movable vertically and guided by theupward extension I91 of arm I93. This arm I95 has a downward tongue I96adapted to bear in the vertical movement of said arm on the downwardextension I98 of arm 193, and arm I93 has a downward tongue I99.

As the tone arm swings to end the playing of a record whose stylusgroove terminates spirally in the middle of the record, the tongue I99strikes the end of a screw 299 threaded for adjustment in the arm "I ofa bell crank lever 292 whose other arm, 293 engages between stops 294,295 of the long horizontally slidable rod 296; but if the stylus grooveof the record being played terminates undulately in the middle of therecord, the tongue I95 of arm I95 rides up an incline 291 (raising thisarm) and slips over the ratchet teeth 293 of a horizontal bar 299 on thearm 2I9 oi! another bell crank lever2|| whose other arm 2|2 also engagesbetween the stops 294, 295.

Ineither case, the lever arms 29I, 2I9 are thus swung from each otheragainst the pressure of the aforesaid spring 2|3, the other lever arms293, 2I2 being thus moved into engagement with stop 234 and causing rod293 to slide toward the left hand side 01 Figures 11, 16 and 23. By thismovement the end portion 229 of long rod 295, (which during the playingof the record has been supporting the vertical rod 2|5 in raisedposition, see Figures 31, 23, 24 and 25), is withdrawn from the keeperhole 2I5 and falls in a vertical slot 2I3 until it rests on the bottomof this slot. Thus the vertical rod 2I5 is permitted (at the end 01'playing the record) to fall and in so doing swings downwardly theconnected arm 221 of a shaft 233 (seeFlgures 31, 16, 2 and 1). and alsothis shaft's other drm 229 whose wrist pin 239 turns in the. upper endof the vertical bar 99 which carries at its lower end the clutch member32, and thus causes this clutch member to engage clutch member 93. sothat the cam disks rotate again to reverse the action of the tonearm-moving means and then the action oi. the record-transferring meansand return the record to its place in the rack. a

This vertical bar 93 has a slot 23| in which wrist pin 239 moves, topermit the unclutching of these clutch members 92, 93 although arm 229may be in the position seen in Figure 5. The bar 39, rods 2|5, 293 andmember 2" being in lowered position wherein said clutch members 92, 93

These rods III, 296, member 2" and bar 99 are raised tothe position seen in Figure 31, (thus disengaging clutch members92, 93)by the aforesaid spring 232 surrounding an adjustable screw post 233 andbearing on block 2I9. The rotation of toothed disk 98 causes the cam 234on its under side to engage and press downwardly the arm 231 of a lever235 travelling in a groove 236, whose other arm is pivoted to a verticalbar 238 (see Figures 19,20, 21 and 1) and thus raises this bars lowerend from the keeper notch 239 of horizontal bar 11 against the pressureof spring 249 (see Figures 1, 5 and 6). Thus released, this bar 11 isslid toward the right hand side of Figures. 1, 5 and 6'by a spring 241.By this action lever catch 89 moves from its position seen in Figure 5and its end 8| moves into engagement with the lower end of lever 82, andthe left hand end 248 of arm 12 falls into engagement with the middle orweb portion 1|- of catch 51, and also the shoulder 13 of arm 12 fallsinto engagement with the upright extension 14 of bar 15. Thereupon thearm 24| of a vertical shaft 242 strikes the adjustable stop 243 carriedby bar 11 and slides this bar toward the left hand side of Figures 1, 5and 6, thereby turning the catch 61 and the lever 82 and moving the bar15 to their positions seen in Figure 1 and causing the clutch member 36,31 to engage, and also sliding bar 81 toward the left hand so that itsinclined portion 89 disengages clutch member 92, 93.

In this left hand movement of bar 11, the horizontal bar 15 moving withit, tensions springs 18 and 241, and the vertical bar 238 drops intonotch 239 of bar 11. The vertical shaft 242 is turned (tocause its arm 2to strike and slide the bar 11) by the toothed cam disk 98 meshing withsaid shafts. gear 244.

The playing of a record. may be stopped at any a when energized, swingsarmature lever 2 to' move rod 295 toward the left hand to thus allowclutch members 92, 93 to engage and cause the cam disks to rotate andreturn the tone arm and the record from the turntable to the rack(Figure 31). The circuit '253 to the motor I4 is opened and closed by amaster switch 254.

The means for selecting the record (or recordside thereof) desired to beplayed, may manii'estly be operated or controlled otherwise than by themeans shown, as by coin-operated mechanism and the like. The armaturelevers 54 may be yieldingly held in swung position by suitable means, asthe pivoted arms 255 whose notches 256 receive their pins 251 (Figure8).

Any number of records may be selected at the same time for playing byclosing the circuits 55 (by their button switches 51), and the recordsthus selected will be played in the order in which the lugs 41corresponding thereto engage (by another arm 213 engaging the lower arm214 of a leveriulcrumed at 215 whose upper arm 215 is connected to thepivotally mounted support 211 of a mercury switch or circuit opener andcloser 218 in the electric circuit 253 containing the motor I4 (seeFigures 1 and 31). This switch being closed and said circuit beingclosed by the master switch 264 to operate the motor, and the buttonswitches 61 corresponding to the records selected for playing being alsoclosed, the action of the machine as hereinbefore explained causes theenergized magnet 66, or 62 (corresponding to one of selected records) toswing its armature lever 64 to the dotted line position seen in Figure 8whereupon the rotation oi shaft 42 causes the corresponding lug 41 toengage its trigger 44 to initiate the playing of said record, this firstrecord to be played thus corresponding to the first one of the lugswhich by the turning of shaft 43 is brought into operative engagementwith its trigger.

In the armature levers movement to dotted line position (Figure 8) itcontacts the horizontal bar 210 (which extends along all the armaturelevers in the same relation therewith) and thus swings arm 21! towardthe dotted line position seen in Figure 8 and the other arm-213 towardthe right hand side of Figure 1. This action swings lever arm- 214 andthereby the mercury switch 216 to closed position, thus closing the maincircuit 253 containing the motor (this circuit's master switch 254 beingalready closed).

The same movement of lever arm 213 carries its horizontal link 219 inthe same direction, moving this link's stop 266 so that the lever arm 61may turn from its position shown in Figure 1 to that seen in Figure 5,and so that the actions hereinbeiore described may follow in the playingof the record.

The first one of the series of selected records having been played, theothers so selected are (as above stated) played'successively and in theorder in which the lugs 41 corresponding thereto are brought by therotation of shaft 43 into engagement with their triggers 46respectively. The operating parts 61, 12, 15, etc. remain in theposition shown in Figure 5 during the playing of all the records thusselected; and when the playing of the last one of said series iscompleted, these Parts are moved, as hereinbefore explained, to initialposition, during which movement the spring 2" draws arm 213 toward theleft hand side of Figure 1 and opens the mercury switch 216,

and also moves the horizontal bar 211 to its solid line position seenin' Figure 8 whef'ei'r'i'it engages all the armature levers 64 in theirsolid line position shown in that view. These armature levers may belocked in that position by a horizontal bar 262 engaging them andcarried by the arms 2" of a lever fulcrumed at 264 whose other arm 266maybe locked by suitable means to the part 266 (see Figures 1 and 10).Thismay be efi'ected manually by pressing the arm 266 against or inengagement with a fixed bracket 266, or by a magnet (not shown) mountedon the bracket which actuates the arm and its bar 262 when the magnet isenergized.

The record disks 22 (of larger and smaller diameters) are held in'therack designated generally 6 with their central holes in registry wtiheach other. This rack, as shown in Figure 29, comprises a plurality ofcompartments-one for each record disk-formed by spaced upright plates260, 26! receiving the record disk therebetween.

A horizontally disposed record-supporting member 262 is moved in itslongitudinal direction through the hole 263 in one (266) of said platesand into the central hole 264 of the record by the inserting movement ofthe record into its compartment. This member 262 is formed at one end ofa lever or rock member 266 pivoted at 266 on said plate to swing in aplane at right angles thereto, and is pressed by a spring 261 to theposition seen in the two right hand compartments in Figure 29; but whena record is inserted, the record engages the opposite end (which is aspring 266) and presses this rock member or lever 265 to move thesupporting member 262 through the holes 263 and 264 as seen in the twoleft hand compartments in this view, thus supporting the records withtheir holes 264 in a level line curved concentrically about theturntables axis.

As the upper r 0 is forced radially outwardly its lug 28 (Figures 19,20) engages the collar 283 sliding on the rod 264' and compresses acoiled spring 265; and as said bar is forced inwardly said lug engagesthe sliding collar 286' and compresses coiled spring 261'; so that ineither case this bar when permitted to return to medial position isassisted in such movement by the compressed spring.
